All three methods publish the same token. Tokens look like `pub__<32 hex characters>`. You pick one method; you don't need all three. | Method | Where | Exact value | How PolyEmbed checks | | - | - | - | - | | `dns` | TXT record on the domain itself | `pm-widget-verification=` | Public DNS lookup through Google DNS. Passes if any TXT record on the name contains the token | | `meta` | `` of `https://` | `` | Fetches the homepage over HTTPS. Passes if the HTML contains the tag exactly as shown | | `file` | `https:///.well-known/polyframe-verification.txt` | `` (nothing else) | Fetches the file over HTTPS. Passes if the trimmed body equals the token | ## Rules * Checks use HTTPS and don't follow redirects. The meta and file URLs must return `200` directly. * Each check times out after five seconds. * Requests come from the user agent `polyembed-domain-verifier/1.0`. Allow it through bot protection or a firewall if checks fail. * For the meta method, the tag must appear in the HTML your server returns, with the attributes in the order `name` then `content`. * Verification covers the domain and all of its subdomains. Verifying `www.example.com` doesn't cover `example.com`. * Each domain belongs to one publisher account. * You must accept the Publisher Terms before running a check. ## Domain statuses | Status | Meaning | | - | - | | `pending` | Added; waiting for a successful check | | `verified` | Ownership confirmed. Widgets can render here | | Suspended | Disabled after review.
